You're right, you do have a really bad girl problem.
Namely, that you need to stop acting like one and grow a pair. :)
That made me lol.
I'm not from this forum either, just stopping by randomly cause google images lead me here randomly.. yeah.. don't ask.. I'm bored on my night shift.
What you need to do.
1. Talk to her ASAP.
2. Don't sound panicky or scared or timid. What girl wants to date a guy like that?
3. Admit you made a mistake and ask her out to do something with you.. and have something in mind to do.. like.. ****... idk how old you are so that kind of limits stuff. If you are younger than 21, dinner/movie/mall/whatever. Older than 21, find some friends (not sure how many you have) and go to a bar or club.. preferably a goth one.. haha. shoot..
4. Then just play it cool. If she smokes, she pokes. If she's goth, she's probably a freak..ya know..
Don't worry man.. just man up, and get to it. Peace.
